Liquid crystal compound, polymerizable liquid crystal composition, optically anisotropic material, optical element and optical information recording/playback device |
| abstract |
Provided are a liquid crystal compound having good light resistance, a polymerizable liquid crystal composition and an optically anisotropic material. Also provided are an optical element having good light resistance and an optical recording/playback device wherein said element is used. The liquid crystal compound is represented by the general formula CH2=CR1-COO-(L)k-E1-E2-(E3)m-R2. E1 is preferably a trans-2,6-decahydronaphthalene group and E2 is preferably a trans-1,4-cyclohexylene group. A phase-difference plate (4) produced using this compound has good light resistance and so it is possible to make an optical head device suitable for larger capacities using a blue laser for the light source (1). |
